Epigenetic regulation of proprotein convertase PACE4 gene expression in human ovarian cancer cells.
Proprotein convertases (PC) are a family of serine endoproteases that play important roles in regulating cell function by converting proproteins to biologically active molecules. Several lines of evidence suggest that overexpression of PCs contributes to tumor formation and progression in various types of cancer. In this study, we examined PC expression in six normal ovarian surface epithelium ...
متن کاملProprotein convertase PACE4 is down-regulated by the basic helix-loop-helix transcription factor hASH-1 and MASH-1.
PACE4 is a mammalian subtilisin-like proprotein convertase that activates transforming growth factor (TGF)-beta-related proteins such as bone morphogenetic protein 2 (BMP2), BMP4 and Nodal and exhibits a dynamic expression pattern during embryogenesis. We recently determined that the 1 kb 5'-upstream region of the PACE4 gene contains 12 E-box (E1-E12) elements and that an E-box cluster (E4-E9) ...
متن کاملSubtilisin-related Proprotein Convertase Endoproteolytic Site*
The human thyrotropin receptor (TSHR) undergoes proteolytic cleavage closely upstream to amino acid 317. Between residues 261 and 313 are three clusters of positively charged amino acids, arginines (Arg) and lysines (Lys), which are potential subtilisin-related proprotein convertase sites. We used oligonucleotide-directed mutagenesis to perform conservative amino acid substitutions within these...
متن کاملIs there a link between proprotein convertase PC7 activity and human lipid homeostasis?
A genome-wide association study suggested that a R504H mutation in the proprotein convertase PC7 is associated with increased circulating levels of HDL and reduced triglycerides in black Africans. Our present results show that PC7 and PC7-R504H exhibit similar processing of transferrin receptor-1, proSortilin, and apolipoprotein-F. Plasma analyses revealed no change in the lipid profiles, insul...
متن کاملPrediction of proprotein convertase cleavage sites.
Many secretory proteins and peptides are synthesized as inactive precursors that in addition to signal peptide cleavage undergo post-translational processing to become biologically active polypeptides. Precursors are usually cleaved at sites composed of single or paired basic amino acid residues by members of the subtilisin/kexin-like proprotein convertase (PC) family. In mammals, seven members...
